v2.5, one jar from 1.18 to 1.21.x
Small but important follow up to 2.4. The plugin would load on 1.20.5 and above (including 1.21.x) but it would actually crash the moment you walked around with a trail enabled. That is because four particle names were renamed in 1.20.5 (SMOKE_NORMAL, DRIP_LAVA, DRIP_WATER, ITEM_CRACK), and the code was holding references to the old constants directly.
What changed
A small Particles helper now resolves each particle by name at startup, with the old name tried first and the new name as a fallback. So the same jar will pick up SMOKE_NORMAL on 1.20.4 and below, and SMOKE on 1.20.5 and above, without any config changes from your side.
Compatibility
One jar now covers 1.18 all the way through 1.21.x. No separate builds, no manual swapping.
That is the only behaviour change for 2.5, everything else from 2.4 carries over as it is.
